Hope everything is OK, thanks for the reply.Unfortunately not - some personal circumstances mean I now need to be away from home for a period. Talk about bad timing
However, the WiiM Home website states "Plug your USB disk into the WiiM Amp and transform your home into a personal concert hall. Stream your digital music collection in studio-quality to multiple WiiM devices throughout your space. The WiiM Amp not only indexes your music library but also serves as an always-on media server, making your personal tunes accessible anytime, anywhere in your home."
The "always-on media server" description does seem to suggest that it'll appear as a media server on your network, the same as if you had a media server on your NAS.

Thanks for measuring. Standby/off seems too high to me. Thats 52kWh per year!
Is this even compliant with european law? I think off should be <0.5Watt and standby <0.8W.

Agreed: I think turned off state should be <0.5W for EU compliance AFAIK.
The requirement for 0.5W in standby does not seem to apply to devices with WiFi. If you want to be able to start streaming from the app on your mobile then the amp has to be connected to Wifi.

I’ll double-check that hopefully sometime next week when I return home - it was done in a bit of a rush and I probably didn’t let it fully turn off.
I didn't dig too deep in the EU paper, but I think only for network devices like routers higher limits are allowed.
See "HiNA" https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32023R0826
Also the Wiim Pro was measured in this forum with <1W.

Ok thanks!
Many devices have different standby modes. For example, my CA Evo 150 has an Eco mode (presumably to keep the EU happy) and a network standby mode. In Eco mode, you cannot bring the Evo 150 out of standby from the app. In network standby, it works as intended and, if I remember correctly, uses about 6W.

Networked standby rules seem to be 2w to 7w or 8w.

If it was the much lower limit mentioned, most wifi smart plugs would fail…

I think the 2-7/8W limit is only for HiNA-Equipment relevant.
BTW: a current Apple TV has a standby power consumtion of 0.5W.

Hi Team,
Before sharing specific power consumption data, it's essential to note that the WiiM Amp does not currently support network standby mode. This means it doesn't adhere to network standby modes' typical power consumption requirements, which are generally under 2W in the EU.
However, the WiiM Amp is designed with power efficiency in mind. It automatically transitions to an idle mode to conserve energy. While in this mode, the power consumption is approximately 3W. Despite being in idle mode, the WiiM Amp remains fully responsive and can be operated instantly through the app or voice commands.
I also attached the Sonos product's power consumption numbers in idle mode for your reference. For Sonos Amp, the power consumption is 7.3W and 6.8W with US and EU power supplier.

Stay tuned for more detailed power consumption data, and thank you for choosing WiiM for your audio needs.

There is nothing wrong with 3W of standby power for me. It's the same as my YAMAHA AVR.
Maybe when the TV sends a signal to the HDMI of the WiiM amp, the amp automatically wakes up and plays audio? In other words, is there no need for troublesome input switching?

And no word on the specific DAC chip until someone does a teardown?
Wiim are not alone.
‘Rotel is also being coy about which ESS Labs DAC chip sits at the centre of the RAS-5000’s internal DAC circuit.’

Or maybe just look at the technical spec here?
It’s an ES9018.

To be fair, I only saw it yesterday and it‘s dated one day earlier, so maybe fits into the “breaking news” category

SnapTo be fair, this looks relatively new

I am surprised that new designs are still using that chip model: it is 10+ years old by now. Nothing against the chip or the decision from me. I have owned DACs with 9018 and I was happy with them. It's just interesting because the Chi-Fi industry is always jumping onboard the latest model as soon as they are released. So WiiM not only moved from AKM but also kept to a well known DAC in their decision.Or maybe just look at the technical spec here?

9018=>9028=>9038 AFAIK.
Edit: by the specs they used the ES9018K2M version, which is a newer, stereo and low power version than the original ES9018, large and 8 channel.
